Bazooka Bass Tube Unique Features:

The grill is both decorative and protective, preventing the Subwoofer from accidental damage from other items, such as golf clubs, groceries or book bags that might be tossed into the cargo area where the Bazooka Woofers are typically mounted.

Bazooka's highly efficient, customized woofers are specially designed and reinforced for use in the Bazooka Bass Tube enclosure, producing a pure piston action and generating the maximum bass output possible.

Edge Roll
All Bazooka Woofers used in Bass Tube enclosures feature large, high excursion, lightweight foam edge rolls to maximize their efficiency and overall bass output.

Tube Enclosure
A tube is a natural pressure vessel, and Bass is about pressure. The patented Bass Tube enclosure creates a natural, uniform, hydraulic transfer of the Bass energy produced by the woofer.

The port opening between the Tube Enclosure and the Port Tube allows for efficient transfer of bass. Bass Tubes enclosures utilize "Bass Reflex" technology to take advantage of both the forward and backward of the woofer, wasting no bass energy.

Port Tube
The bass energy created by both the forward and backward motion of the woofer are time aligned so that 100% of the woofer's output is concentrated into one output point.

Acoustic Damping Fiber
The acoustic damping material helps lower the resonance of the enclosure and simulates an increased air space.

Integrated Amplifier
The integrated amplifiers are performance matched to the specific woofers used in Bass Tube enclosures to ensure that every watt of power is efficiently turned into bass performance. Having the amplifier integrated into the enclosure simplifies the installation and eliminates power loss.

Corner Loading
Bass Tube enclosures are specifically designed to take advantage of the natural amplification characteristics that occur when a subwoofer is placed into the corner of a vehicle. The corner acts like a megaphone, substantially increasing bass performance.

How Do I Install a Bazooka Bass Tube?

Installation is Simple! The bass tube comes with straps to keep the sub securely mounted, while still making removal quick and easy if you need even more cargo room. Optional Chrome-Plated UMS Brackets give a flashier look, as well as a more secure, permanent mounting when removal isn't a problem.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
150 watts
Total Peak Power Handling
This is the Total Peak Power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.

Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements.
150 watts
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Paper Cone with Polypropylene Dust Cap
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Treated Foam
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
102 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
35 - 250 Hz
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Vented / Ported
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
The height of the item, measured from top to bottom, in inches.
The width of the item from left to right (side-to-side) measured in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
Terminal Type
Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Nickle-Plated screw terminals
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

Surprising sounds for the seasoned ear

April 6, 2011

As an electronic and acoustic engineer I have had many systems in my vehicles for the last twenty years. Every brand of subwoofers has been tested and it has to be said that products from the JL stable have been my favorite listen for some time now.
Just their shear ability to play hard, go ridiculously low and sound so musical and accurate make them a great listen, especially my favourite a 15w3v2 in a ported 3cu Ft enclosure.
On a trip of nostalgia I spotted two 8" bazooka tube's BT8014's the unamplified versions going cheap on ebay!
Although already very happy with my current alpine / jl setup, I decided to buy the two tubes not wanting to turn down what seemed like a veritable bargain.
The tubes are very tiny and lightweight due to the all plastic tube design. On removing the drive unit, the inside consists of a vented tube, a piece of loft insulation and an inductor coil which is wired in series onto the speaker wires.
With the coils in place and running from an active JL 500/1 the speakers sound muddy and underwhelming. By removing these basic 6db crossover coils, the speakers really seemed a lot more bright and forward sounding.
Two of these placed inside a renault kangoo van, not corner loaded but placed parallel vents facing forward. The sound produced was startling strong deep controlled punchy bass.
Not bad for two 8" cheapo drivers rated at 100watts running in parallel from a 500watt JL amp!
No hint of distortion and lots of clean punchy multi note bass.
Okay no match for my favourite 15" JL, but great for a good bass injection without disturbing the neighborhood.
My value rating of 5* is based upon the low price these are available at!
These days for not a lot of money its possible to buy very cheap speakers which sound great in a simple mdf box.
But for the size and shear performance on offer these 'back in the day - tubes' are still a great purchase at the right price...

Perfect fit, great sound, at the right price.

September 14, 2010

I purchased this specific model due to available space in the back of an old jeep wrangler, and because the price was right. . It fit extremely well, and much to my surprise the sound quality was just perfect for this size vehicle. Solid, but not overpowering, but I also know I could blow the doors off whoever pulls up next to me, and tries to share their unsolicited music with me. Great sound for the price, and arrived quick too.

Great Value

August 17, 2010

I bought the Bazooka BT8014 for my son. He wanted a subwoofer for his single cab pick-up but didn't have the room. This turned out to be a great alternative and was easy for him to install. He enjoys it very much.

I bought a Bazooka 8 in. speaker and really liked that it fits almost anywhere and doesnt take up much space the cons on the speaker is that it keeps on rolling in my trunk i really dont know if they come with some kind of harness or straps to it but didnt see that in the box.
